GAIUS C. -MOORE, OF ROCHESTER, NEW YORK, A SEIGNOR. TO JOHN C. MOORE CORPORA- TION, OF ROCHESTER, NEW YORK, A CORPORATION OF NEW YORK.

LOOSE-LEAF BINDER.

following is a specification.

This invention relates to loose leaf binders and pertains more especially to that class of such binders-in which the posts are sectionally extensible, that is, built up in sections which may preferably be similar tially in vertical central section and and interchangeable, for the puropse of adapting the binder to hold any desired number of leaves, and changing the dis tances betweenthe covers accordingly.

The object of my present invention isto provide a binder of the class described, in which the clamping plate carried by the upper cover section may be removed from the rest of the binder and thereafter the leaves in the binder divided at any desired point and those leaves above such desired point all removed together and held in positive alinement by mechanism adapted also to control their ready re-insertion in the binder in perfect alinement with the leaves already therein. For this purpose I make use of a plate beneath the clamping plate and provide such plate with sectional posts adapted, when in proper position, to be held in alinement, referably regardless of the leaves engaged y the osts thereon.

The accompanying rawings illustrate a loose leaf binder made in accordance with my invention and'are as follows :Figure 1 is a perspective view of the binder as seen from therear and one end. Fig. 2 shows in elevation the post carrying plates separated and the posts therein and with all the parts to the right of the center shown in full, while to the left of the center, such parts are shown in vertical central section, the closed positions for the parts being indicated in dotted lines. Fig. 3 shows parartially in side view one of the sections 0 the impaling posts. Fig. 4, which is drawn to a reduced scale, shows the parts seen in 2, but with each of the posts therein as having been elongated by the addition of another section thereto. Fig. 5 is an end view of the parts seen in Fig. 4. Fig. 6, drawn to thesame scale as Fig. 4, is a plan view of a part of a leaf adapted to use in such binder.

Specification of Letters Patent.

Application filed February Z, 1909. Serial No. 475,573.

Fig. 7 shows the parts of the lower cover and the impaling posts carried thereby with leaves engaged by such posts, but with the upper post carrying plate removed. such upper post carrying plate with leaves held thereby, being shown in Fig. 8, as having been removed from the binder, after first of course, removing the cover and the thereto attached clamping plate.

Similar letters refer to throughout the several views.

Referring to the drawings :B is the upper cover flexibly united at b to the inclos-ed clamping"- bar G which is preferably bound withthe same material as the rest of the cover. I

B is the lower cover sectionfiexibly united at b to the. member D comprising the similarly bound bottom plate D The internal mechanism of the clamping bar within the member G is substantially that shown in United States Patent No. 872,968, issued Dec. 3, 1907, to Milan \V. Patric, and is operable by means of a suitable key insertedin the key hole 5/ and by means 'of. which the member (I; may be clamped'to the posts P at any desired point vertically thereon.

\Vithin the member D is contained the bottom plat-e1) in which are rigidly secured the lowersections d of the sectional posts 1.

similar lHll'iH C is the upper plate having holes there through adapted to receive the posts P and having also'rigidly secured therein the upper sections 0 of the sectional posts P The posts P and P are sectionally extensible to any desired length by the addition of sections (1. which may be screwed therein, one of such sections being seen in Fig. 3 and all of such sections bein exactly alike. D is provided with tapered studs vwhich are adapted to engage in the openings or holes at the lower ends of either of the sections 0 of the posts P or the lowermost sections a of the posts P when any desired number of such sections a are added thereto.

To add to the appearance of the binder. in the threaded holes a in the upper ends of the sections a of the posts P, there may be inserted threaded terminal pieces 25 adapted to facilitate the insertion thcreover of the plate C or the member G.

In using my hinder, the clamping mechanism within themember G is released fromthe posts P by means of the key inserted The plate within the opening 9 therefor and the cover B with the member G is removed from the posts P and thereafter the plate C is removed from the posts Pand the posts P are made of the desired length by the insertion of the proper number of sections at having the reduced and externally threaded portion 0. adapted to be screwed into the threaded hole a in the other end of the adjacent and similar section a. The posts I? are also similarly built up to the desired length as indicated in the drawings. In removing any desired leaf from the hinder the cover B with the member G is removed and the leaves separated at the desired point and all above such point are'removed with the plate C as indicated in Figs. 7 and 8 when the desired .leaf may be removed or others inserted. In this way a leaf may be inserted or removed at any desired point within the binder.

From the foregoing description it is believed that the construction and method-of using my binder is .sufiiciently clear to call for no further explanation.

In the following claims, I shall make use of the term sectional impaling post meaning thereby an impaling post built up in' sectlons, which are preferably similar and interchangeable, whereby the post may be made of different desired lengths, andimpaling posts each comprising a, plurality of --such sections; two binder plates, each carrying impaling posts formed of such impaling post sections and one of such binder' plates provided with holes to receive the im aling posts, carried by the other plate an also with clamping mechanism adapted to engage and clamp such posts extending therethrough carried by the other plate, s'uch binding post sections, such plates and such clamping mechanism so cooperatively proportioned that, when the posts, carried by the plate provided with the clamping mechanism extend substantially to the other plate, the posts carried by such other plate will extend upwardly through the holes therefor in the plate carrying the clamping mechanism so as to be engaged thereby at all times upon the addition to or-removal from each of the posts carried by each of such plates of the same number of such impaling post sections.

2. 'A series of substantially-similar and interchangeable impaling post sections adapted to be brought into interlocking engagementsuccessively one with another to form impaling posts each comprising a plurality of such sections; two bmd'er plates, each carrying impaling posts formed of such impaling post sections and one of such binder plates provided with holes to receive the impaling posts, carried by the other plate, and also with clamping mechanism adapted to engage and clamp such posts extending theret-hrough carried by the other plate, such binding post sections, such plates and such clamping mechanism so cooperatively proportioned that, when the posts, carried by the' plate provided with the clamping mechanism extend substantially to the other plate, the posts carried by such other plate will extend upwardly through the holes therefor in the plate carrying the clamping mechanism so as to be engaged thereby at all times upon the addition to or removal from each of the posts carried by each of such plates of the same number of suchimpaling sections and means carried'by the plate carrying the posts extending through the plate provided with the clamplng mechanism for releasably engaging the posts carried by such plate provided with clamping mechanism independent of the number 0 sections in such last named posts.
